Eau Claire
Note: due to lag time between exposure and final positive test, effects of changes are typically observed about two weeks after event.
Wisconsin
Comment: Why a 7-day moving average? Wisconsin tends to have cyclical patterns in testing results, with low spots typically on Mondays (this may be due to lower testing on weekends)
Active
Active cases: Estimated recovery time from health experts varies between 10-20 days, with rare cases being long-term / on-going. Even given the testing lag, a conservative approximation is to use the total number of positive (diagnosed) cases across the last 10 days. We will go with this standard, along with a range from 8-12 days of active accumulation, and adjust as more precise information becomes available.

Scientific References for Common Questions
Masks Should I wear a mask in enclosed public spaces? Unequivocally, YES. References for reasoning, using a current (as of July 8) accumulation of over 70 references. A few of my favorites (modeling-wise) are:
- Physical distancing, face masks, and eye protection to prevent person-to-person transmission of SARS-CoV-2 and COVID-19: a systematic review and meta-analysis
- Background for modelling: A modelling framework to assess the likely effectiveness of facemasks in combination with ‘lock-down’ in managing the COVID-19 pandemic
- To mask or not to mask: Modeling the potential for face mask use by the general public to curtail the COVID-19 pandemic
- Face Masks Considerably Reduce COVID-19 Cases in Germany: A Synthetic Control Method Approach
A couple more in the works:
- Face mask wearing rate predicts country's COVID-19 death rates
- Association of country-wide coronavirus mortality with demographics, testing, lockdowns, and public wearing of masks (Update June 15, 2020)
- Physical distancing, face masks, and eye protection for prevention of COVID-19

[1] "The number of cumulative deaths, at a lag of 20 days, are approximately 9.8 times number of cumulative cases to the 0.44 power."[1] "We thus predict that on 2020-08-29 the cumulative number of deaths in WI will be 1211"
